Revive server version or Unify with Lambda

[anjishnu]

After focusing on Lambda for a while to get the core library down - I think we are at the point that we can start looking at having a simple push-button server implementation as well.

The main issue with the server implementation is the SSL hell I had to go through when I wrote my first alexa skill: visible in gory detail here: https://github.com/anjishnu/ask-alexa-pykit/blob/cherrypy_0.3_release/lib/validation_utils.py

This also introduced a PyCrypto dependency (and literally shelling out to OpenSSL) to the library which was a big mess. We should be able to replicate this without relying on too many external libraries, and hopefully python's ssl module is up to the task.

I didn't want to spend too much time on it because it ended up in a dead end where it was impossible to publish anything because of the trusted SSL cert authority requirement - with this that might also be possible for free https://console.aws.amazon.com/acm/home?region=us-east-1#/firstrun/
